the broken URL comes from my ~/.signature which since about 2 months
contains the following fragment:

http://info.comodo.priv.at/{,blog/}

& probably that line was found in some web archive of a mailing list or
newsgroup or somesuch.
now what is this highly intelligent Twiceler thingy? a look at the URL in
the access.log entry redirects to cuil, & the page
proudly claims in friendly, large, green letters

Cuil is the biggest search engine on the planet.

apart from the fact that I've never heard about them & that their search
results are not impressive either, their "philosophy" (huh?)
page claims:

Size matters

maybe it's just me but probably they should invest more in technical
"cuil" [0] than in marketing speak that sounds less like search
engines but more like another business branch on the intarwebs.
